SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures that the original data (docs/career/my_career_data.md) and all rendered templates (docs/career/resume.md, docs/career/career_portfolio.md, and the templates in templates/) stay in sync, preventing drift between source data and generated outputs.

Core Features & Use Cases

  • Consistency checks across Markdown sources and HTML templates to identify mismatches in data, dates, roles, and technical stacks.
  • Automated delta reporting that highlights before/after values and provides a concise summary of discrepancies.
  • Use Case: after updating the source data, run the check to generate a discrepancy report and a synchronization summary for the maintainers.

Quick Start

Run the comparison workflow described in the SKILL.md to produce a mismatch report and a summary of synchronization status. Use this skill to verify that all affected files reflect the latest source data.

FAQPage Schema
How do I check data consistency between Markdown sources and HTML templates?▼

Data consistency checks compare original source data against rendered Markdown and HTML templates to identify mismatches in dates, roles, and technical stacks, then generate a discrepancy report highlighting before and after values.

Why does my rendered Markdown portfolio drift from the original career data?▼

Rendered Markdown drifts from original career data when source files are updated without regenerating dependent outputs. Running an automated synchronization check detects these mismatches and provides a summary of discrepancies for maintainers.

What is the best way to automate data synchronization validation across generated files?▼

Data synchronization validation is best automated by running file comparisons against a single source of truth to detect mismatches and output a concise delta report without requiring external libraries.

Do I need external libraries to perform a consistency check on Markdown and HTML templates?▼

No external libraries are needed to perform a consistency check on Markdown and HTML templates. The validation relies on simple file comparisons and built-in report generation to identify data mismatches.

Can I generate a mismatch report for data validation without external dependencies?▼

Yes, you can generate a mismatch report for data validation without external dependencies. The process uses simple file comparisons to identify discrepancies between the source data and rendered templates and outputs a summary.
